SCRAPER.ND LEVELER. V

To all whom 2'1; may concern:

- Be it known that I, HARRY V. Monnrs, a citizen of the United States,residing at Woodland, in the county of Yolo and State of California,have invented a new and useful Scraper and Leveler, of which thefollowing is a specification.

The subject of this invention is a scraper and leveler used for scrapingand leveling land, especially land intended to be flooded for irrigationpurposes.

The main object of the invention is the provision of a scraper andleveler which may be readily drawn by a tractor and which will removesoil from. high spots and deposit the same in low places.

Another object of the invention is the provision of means for depositingthe earth collected by the scraper 1n ridges or checks.

Another object ofthe invention is the provision of means for adjustingthe position of the scraper blade. 1

Another object of the invention is the provision of means for releasingthe scraper blade for rotation.

Another obj ectoi the invention is the provision of means forautomatically restoring the scraper blade to operative position.

The invention also contemplates generally improving the construction andenhancing the utility of scrapers and levelers.

With the foregoing and other objects in view,- which will appear as thedescription proceeds, the invention. resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and --claimed, it being understood that changesin the preciseembodiment of the invention can be made within the scope of what isclaimed without departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in theaccompanying drawings,

Fig. 4 is a detailsectional view taken on theline 4 t of Fig. 1;

F ig. 5 is an enlarged detail taken on the line ;5.- 5 of Fig. 2; a 1

Specification of Letters Patent. Patented Bla r, 16, 1920, Applicationfiled. October 1 4, 1918. Serial No. 257,973;-

Referring to the drawings by numerals of 1er"erence: v i

In carrylng out the invention, a pair of runners 1 are provided, whichare arranged 1 l in parallelism and whichare connected by the crosspieces 2, and by the angled braces 3. Lug bolts st are secured in theforward ends. or the runners andthe forward cross piece 2, and chains 5aresecured to the eyes. I

formed at the 'fOlWfllfl ends of these bolts for the purpose ofconnecting the scraper to a tractor or the like. Boards 6 maybe se curedacross the runners 1 to form a platform upon which the operator maystand. Side pieces 7 may besecured to the upper edges of the runners 1,near the rear ends thereof, and these side pieces extend for a shortdistance longitudinally of the runners.

1 at a point between the ends of the runner, and upon this shaftispivotallyniount ed, for oscillation. thereabout, the forward end of aside supporting strip 9. Each sup- A stub shaft 8 is securedto eachrunner porting strip 9 is apertured to journal a shaft 10, preferablyformed of tubular material, the ends of which extend aterally beyond thesupporting strips.

At diametrically opposite portions of the These planks are ar- L fromundue wear. On the laterally extending ends of the shaft 10 are secured"cross arms 1-1, the arms, preferably, being set to form 1 angles ofsixty degrees with each other and with thescraper blade formed of theplanks 11 as just described; I

From the foregoing it will be evident that,

should the scraper blade be free to revolve,

the ends of the cross arms 14. would succes sively engage the groundand, as the-scraper was drawn forward, would rotate thescraper blade.

For the purpose oi. yleldingly supporting the scraper blade, ellipticalsprings 15 are secured to'the lower edges of the side'supports 9, andrest upon brarkets 16 which are secured to the runners 1. The sidesupports 9 are retained in nroper position by having their free endsarranged tooscillate 1n guides 17, which are securedto the runners 1. V

In order that the scraper blade may be restrained against rotation, andreleased through a slot formed in an upright 20,

which is secured to and rises-from one of the cross pieces 2 and whichacts as a guide tion du'e'to the for the lever. The lever is retained inits normal position by gravity, assisted by a retractile spring 21, oneend of which is connected'to the lever 18 while theot'lier end securedto the upright 20. In normal position, a latch 19, formed on the underside of the lever 18, or attached thereto, in position'to contact theupperedge of the scraper blade, at the forward. face of the blade, andSo retain the blade: against rotapressure earth against its lower edge.

The rear end of the lever 18 is bifurcated tostraddlean upright 22,which is suitably secured to one of the cross pieces 2, towhiohthelever' is pivoted by means ofa' bolt or the'like. I Tofpei'nitadjustment of the lever sothat the scraperblade may be held atdesired angles to the vertical. the bolt passes through slots formed fora short distance longitudinally of the prongs of-the bifurcated rearended? the lever 18, and to the rear end of the lever is pivotallycuredthe forward end of an adjusting rod j the rear end of which passesthrough an angle plate 9.5, suitablysecured at the rear endof thescrapen'and is threaded to'receive a nut 26 which may be operated toadjust the position of the lever.

A pair of levers 27 are pivotally secured at thenpper end. of theupright 22,

V I I one'on each side thereof, and these'levers extend long tudinallyof the scraper with their for I wardends positioned adjacent theplatform and within easy reach of the operator. The

i rearends of these levers 27 are connected by links 28 w1th therespective rear ends of levers 29. The levers 29 are positioned belowthe lovers 27 andare supported between theiriend's on supports 30,;whichare Q'suitably secured to the scraper structure.

To therespective forward ends of the levers .29 'are secured hangers31,. which pass through apertures or bores formed adjacent therear endsof the respective sidesupports 9.- fThe hangers 31 are threaded toreceive nuts 32,; one engaging the upper and ,the

other thelower edge of the side supportsO so that the rear ends of thesupports may be adjusted to adjust the depth of cut of the scraperblade; Y

The operation of the device is as follows :When a field is beingprepared for irrigation, or flooding, it is necessary that the saineshould be perfectly smooth, and that no low places should be left, asthe'water would collect therein and drown out the crops. It is alsonecessary that checks be built atproper intervals, these checkslconsisting in ridges of earth of suitable height and thickness for thepurpose. i

' The scraper herein describedand shown consisting of long runners, willinsure the device passing over uneven. land without dropping into everysmall hole or hollow which is passed over. This will insure the earthwhich is collected in front of the scraper bladel .n and smoothed o ttherein. The .i act that the sore blade'niay berraise'd or lowered byactuating the levers 27, also pern'iits the the scraper is drawnover theland and earth collected in front of the scraper blade.

When sufiicient earth has been collected, the-- 1. A scraper andleveler, including a frame, a scraper blade supported in the frame androtatable therein, releasable ineans forlocking the blade againstrotation, and means for adjusting thelocking means to hold the" blade inadjusted positions. 7
